with the lower UJ .
The UJ on the bottom end on the rack is one piece with the lower shaft , so you can only fit the upper UJ in line with the cut outs in the column and it’s totally wrong . Anybody else came across this as it’s bad engineering practice and I am not happy.

On the old joint the bolts runs in line with the UJ , on the new joint the bolt is at 90 Dgs to the UJ. So if you assemble it up one joint would be horizontal while one was vertical . This will make the steering notchy !

The issue is the bolt will only pass through with it in one orientation?

Been a while since I stared at the column UJs and splines but don't some parts have a groove all the way round and others just a slot (so fixing the rotary position)?

The rack has a cut out all the way round so the lower joint fits on in any orientation . It is a sold forging with the shaft . The top of the lower shaft has a notch and the column has a notch as well . So both joints need to be inline or the shaft will rum out of true . Think of it like a propshaft the UJ,s have to run phases together . 2 ways round it cut a groove round the top of the lower column and spin the joint round or get the correct UJ .
